摘要：

Room temperature molten salts consisting of 1-ethyl-3-methylimidazolium chloride (MEICl), AlCl3 and NaCl are of interest as electrochemical agents. Results of Al-27 and C-13 NMR dual spin probe (DSP) relaxation studies of these ionic ligands support the existence of interactions between MEI+ and AlCl4-. The dual spin probe method is used to determine liquid state quadrupole coupling constants of 0.821 and 2.10 MHz for the neutral (MEICl=AlCl3) and neutral buffered (Na+0.22MEI+0.78AlCl4-) melts.
